Study: Warming may threaten Lake Tahoe - Yahoo! News: "A new study predicts water circulation in Lake Tahoe is being dramatically altered by global warming, threatening the lake's delicate ecosystem and famed clear waters.
The University of California, Davis study said one likely consequence is warmer lake temperatures that will mean fewer cold-water native fish and more invasive species — like carp, large-mouth bass and bluegill.
'What we expect is that deep mixing of Lake Tahoe's water layers will become less frequent, even nonexistent, depleting the bottom waters of oxygen,' said Geoffrey Schladow, director of the Tahoe Environmental Research Center at U.S. Davis."
